Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: The Prophet Muhammad (peace be upon him) came to the house of Lady Juwayriya bint al-Harith (may Allah be pleased with her) on a Friday. She was observing a fast. The Prophet (peace be upon him) asked: Did you fast yesterday? She replied: No. The Prophet (peace be upon him) said: Do you intend to fast tomorrow? She said: No. The Prophet (peace be upon him) said: Then break your fast.
